And as you would be building the container image again and again during development to check that your code changes are working, there's a lot of accumulated time this would save.

Then, near the end of the `Dockerfile`, we copy all the code. As this is what **changes most frequently**, we put it near the end, because almost always, anything after this step will not be able to use the cache.

```Dockerfile

  @Override
  public void put(Range<K> range, V value) {
    if (!range.isEmpty()) {
      checkNotNull(value);
      remove(range);
      entriesByLowerBound.put(range.lowerBound, new RangeMapEntry<K, V>(range, value));
    }
  }

  @Override
  public void putCoalescing(Range<K> range, V value) {
    // don't short-circuit if the range is empty - it may be between two ranges we can coalesce.

        LocaleUtil.setDefault(null);
    }

    @Test
    public void testErrorMessage_ja() throws Exception {
